x86/cpu: Change type of x86_cache_size variable to unsigned int
commit 24dbc6000f4b9b0ef5a9daecb161f1907733765a upstream.
Currently, x86_cache_size is of type int, which makes no sense as we
will never have a valid cache size equal or less than 0. So instead of
initializing this variable to -1, it can perfectly be initialized to 0
and use it as an unsigned variable instead.
